Latest / Stuff You Should Know / Testosterone and Estrogen: Wondrous Hormones
Transcript
- 0:01Speaker 1: Welcome to stuff you should know, a production of iHeartRadio.
- 0:11Speaker 2: Hey, and welcome to the podcast. I'm Josh, and there's
- 0:13Speaker 2: Chuck and Jerry's here too, back again on the trip
- 0:17Speaker 2: of a lifetime and it's the Three Amigos, the Three Musketeers,
- 0:21Speaker 2: the Trace Caballeros. Stuff.
- 0:24Speaker 1: That's right, talking about e n t Oi oi oi.
- 0:30Speaker 2: Hey, that was pretty good, Chuck. I was not expecting that.
- 0:34Speaker 2: Sometimes sometimes there's like a little pause in between you
- 0:39Speaker 2: talking and me responding, and it's because I'm just astounded.
- 0:43Speaker 2: And that was a good example of that. You did great.
- 0:48Speaker 1: Yeah, and t Baby, let's do it.
- 0:49Speaker 2: Okay. So we're talking today about testosterone estrogen. What people
- 0:55Speaker 2: commonly think of are the two hormones, the female hormone
- 1:01Speaker 2: the male hormone, and that those are what divides us.
- 1:05Speaker 2: The sexes are binary, they're bisexual, there's male, there's female.
- 1:09Speaker 2: Gender is a totally different topic, as we'll talk about
- 1:13Speaker 2: a little bit. But if you have a lot of estrogen,
- 1:16Speaker 2: you're female, a lot of testosterone, you're a male, and
- 1:19Speaker 2: it turns out that we can trace that that's all
- 1:22Speaker 2: like generally incorrect. It's such a such a broad stroke
- 1:27Speaker 2: explanation of estrogen and testosterone that it actually has tripped
- 1:32Speaker 2: us up all this time. And just from researching this, Chuck,
- 1:36Speaker 2: I learned like, wow, this is if we had just
- 1:38Speaker 2: never considered estrogen female in testosterone male, I think our
- 1:43Speaker 2: general understanding of those two hormones would be so much deeper.
- 1:47Speaker 3: Yeah, and it's one of those things where we can
- 1:49Speaker 3: trace back to a time where that sort of whole
- 1:54Speaker 3: notion came from. And of course, you know, it's early science.
- 1:57Speaker 3: They were trying to figure stuff out. But starting about
- 2:00Speaker 3: the mid nineteenth century is when scientists started kind of
- 2:03Speaker 3: going wild with animals and organs and doing things like, hey, rat,
- 2:12Speaker 3: let me remove your testicles and let me put some
- 2:15Speaker 3: ovaries in you and see what happens.
- 2:18Speaker 1: And there was a lot of this going on.
- 2:19Speaker 3: There was a British physiologist named Ernest Starling who actually
- 2:23Speaker 3: coined the word hormone from the Greek word to excite
- 2:26Speaker 3: in nineteen oh five. And this is sort of right
- 2:29Speaker 3: around that time in the early nineteen hundreds, when there
- 2:32Speaker 3: were other scientists and physiologists doing all kinds of wacky
- 2:36Speaker 3: experiments to see what happened.
- 2:37Speaker 2: Yeah, and we should say hormones are simply chemical messengers
- 2:41Speaker 2: that basically relay messages and trigger responses or keep responses
- 2:46Speaker 2: from happening in the body, and that estrogen and testosterone
- 2:50Speaker 2: are two kinds of hormones, specifically steroid hormones, meaning they're
- 2:54Speaker 2: made from cholesterol, which for some reason I find really.
- 2:57Speaker 3: Gross, so well, you might find this gross too. Then
- 3:04Speaker 3: there's an Austrian named Eugene Steinach who was doing these
- 3:08Speaker 3: kinds of experiments that I was just talking about, and
- 3:11Speaker 3: he was saying, like, came here, frog, let me poke
- 3:14Speaker 3: around your testicles and get some liquid out of there.
- 3:17Speaker 3: Let me, like I said earlier, let me take this rat,
- 3:20Speaker 3: let me castrate it, let me transplant some ovaries onto
- 3:23Speaker 3: this rat, and then observe what happens. And Steinach was
- 3:27Speaker 3: one of those early scientists who kind of led to
- 3:29Speaker 3: this sort of binary idea that you know, if you
- 3:37Speaker 3: do this, you're going to feminize a rat, or you're
- 3:39Speaker 3: going to masculinize a rat if you do that.
- 3:40Speaker 1: Sort of the vice versa operation.
- 3:42Speaker 3: Yeah, but very very quickly there were people even back
- 3:45Speaker 3: then scientists that were like, oh, wait a minute, this
- 3:48Speaker 3: is it's not quite as binary as you're making it
- 3:51Speaker 3: out to be. And there's plenty of examples and reasons why.
- 3:54Speaker 2: Yeah, you could almost lay the entire problem at the
- 3:56Speaker 2: feet of Eugene Steinach. That he was the one who
- 3:59Speaker 2: basically said that humans are bisexual as how we put it,
- 4:02Speaker 2: binary sexes male female, and it depends on whether you
- 4:06Speaker 2: have testosterone or estrogen. And like you said, he got pushedback.
- 4:10Speaker 2: There was one guy in particular, an embryologist named Carl Moore,
- 4:13Speaker 2: who was like, hey, Steinick, stop and think about what
- 4:16Speaker 2: you're saying here, Like, even without your you know, mad
- 4:20Speaker 2: scientist experiments, female rats do all sorts of like quote
- 4:25Speaker 2: male behaviors and vice versa. And even with your flip
- 4:30Speaker 2: flop you know, overreason gonad rats, they're still doing behaviors
- 4:35Speaker 2: that are are not easily assigned to one sex or
- 4:40Speaker 2: the other. So I'm not one hundred percent sure that
- 4:43Speaker 2: it's quite as cut and dry as you you have
- 4:46Speaker 2: have explained it. And Eugene Steinach had Carl Moore murdered silence.
- 4:52Speaker 1: Forever not true at least I don't think it is.
- 4:58Speaker 2: I hope, okay, I just.
- 4:59Speaker 3: Tho you might have just leaned in with a pillow
- 5:01Speaker 3: and gave him the forever Hugin.
- 5:03Speaker 2: That's right.
- 5:04Speaker 3: So flashing forward a little bit too, about the turn
- 5:08Speaker 3: of the twentieth century is when research got a little
- 5:10Speaker 3: more serious about it, and they found that extracts from
- 5:15Speaker 3: your ovaries could have beneficial treatments for things like hot
- 5:19Speaker 3: flashes during menopause, and it could stimulate what's called estros,
- 5:23Speaker 3: which is where the word estrogen comes from. But estris
- 5:26Speaker 3: is like when an animal is in heat. If you've
- 5:29Speaker 3: ever seen a cat or something or a dog in heat,
- 5:32Speaker 3: it's pretty clear that something different is going on, right,
- 5:36Speaker 3: And that word estrogen in nineteen oh six comes from
- 5:41Speaker 3: that word estrus, which is from the Greek word oystros,
- 5:46Speaker 3: which means mad desire.
- 5:47Speaker 2: It also sounds like a brand of.
- 5:49Speaker 1: Yogurt oysters, Yeah, oystros. Yeah.
- 5:53Speaker 2: So once these guys like this is the beginning of
- 5:56Speaker 2: the twentieth century, very late nineteenth but mostly the first
- 5:59Speaker 2: couple decades of the twentieth century, scientists are starting to
- 6:02Speaker 2: isolate hormones, and in particular sex hormones, and they're like, well,
- 6:06Speaker 2: what happens if you give them to humans? Now forget
- 6:09Speaker 2: the frogs and rats and all that stuff. And what
- 6:12Speaker 2: they figured out very quickly is like you said, they
- 6:14Speaker 2: like menopause have been around for a while, and they're like, well,
- 6:17Speaker 2: women have menopause and estrogen seems to be the woman's
- 6:20Speaker 2: sex hormone. Let's give them estrogen and see what happens.
- 6:24Speaker 2: And it actually had a pretty beneficial effect. It's been
- 6:28Speaker 2: long known that estrogen given as like a drug can
- 6:34Speaker 2: treat symptoms of menopause, like hot flashes and stuff. And
- 6:37Speaker 2: the first estrogen, I guess prescription drug. It's called premarin,
- 6:43Speaker 2: which says like a perfectly legitimate, big pharma sound to it, right, Premarin.
- 6:52Speaker 2: That's a great name for a drug. But it's even
- 6:54Speaker 2: better if you know what it stands for.
- 6:57Speaker 3: Yeah, and this is well should we say when it
- 6:59Speaker 3: stands say what it is and then what it stands for.
- 7:03Speaker 2: I think you can do both simultaneously.
- 7:05Speaker 1: Actually, well, it's not a synthetic estrogen.
- 7:09Speaker 3: It was actually a natural isolated estrogen derived from the
- 7:15Speaker 3: urine of a pregnant horse. So premarin stood for pre
- 7:20Speaker 3: pregnant mayor mayor and the end from urine, so pre
- 7:25Speaker 3: maren pregnant horse urine.
- 7:27Speaker 1: Yeah, and it was I believe this is nineteen thirty nine.
- 7:30Speaker 3: It was made of like ten different estrogens and was
- 7:33Speaker 3: available commercially in the US just a few years later,
- 7:36Speaker 3: and by nineteen ninety two was the highest selling drug
- 7:40Speaker 3: in the United States.
- 7:41Speaker 2: Yeah, if you want to have a good idea of
- 7:44Speaker 2: just how crazy the pharmaceutical market has become in the US,
- 7:49Speaker 2: Premarin was the I think you said, the most prescribed
- 7:54Speaker 2: drug in the US.
- 7:56Speaker 3: Well, the best selling I guess sho would match. Yeah,
- 7:59Speaker 3: the hit single exactly.
- 8:01Speaker 2: So this hit single, Premarin in nineteen ninety seven had
- 8:05Speaker 2: revenues of one billion dollars. Pretty not shabby. It'd be
- 8:09Speaker 2: about two billion dollars today. Humera, the second best selling
- 8:13Speaker 2: drug in twenty twenty two, had revenues of twenty one
- 8:16Speaker 2: billion dollars. In that nuts like, that's that's just night
- 8:21Speaker 2: and day compared to how far we've I guess how
- 8:24Speaker 2: far we've come. It's one way to put it. But
- 8:27Speaker 2: the upsot is premar in was it was a lifesaver.
- 8:30Speaker 2: Men were like, hey, I'd like you to be sexually available.
- 8:34Speaker 2: Why don't you take this horse, you're in estrogen, And
- 8:36Speaker 2: when we were like, it solves my hot flash problems
- 8:39Speaker 2: sold so it actually, it really was very popular for
- 8:43Speaker 2: a while, and it wasn't until I think two thousand
- 8:46Speaker 2: and two that it just dropped off precipitously.
- 8:48Speaker 3: Right, Yeah, And we should mention too that this was
- 8:52Speaker 3: you know, it was obviously for things like hot flashes,
- 8:54Speaker 3: but they were also marketing it as a way to
- 8:57Speaker 3: maintain femininity as you age, none other than William Masters
- 9:02Speaker 3: of Masters in Johnson's Fame Sex Crime. They said that
- 9:06Speaker 3: women should use the drug to avoid falling into the
- 9:09Speaker 3: third sex or the neutral gender, which is very off base,
- 9:14Speaker 3: to say the least. But yeah, in two thousand and two,
- 9:17Speaker 3: things change because there was the Women's Tell Initiative released
- 9:22Speaker 3: a study about attitudes that that really like changed everything
- 9:28Speaker 3: when it comes to how women or people in general
- 9:30Speaker 3: think of hormone therapy when they said that it can
- 9:34Speaker 3: cause breast cancer, heart disease, blood clots, and stroke if
- 9:39Speaker 3: you take what was called by this time prim pro
- 9:42Speaker 3: which was Primaran and pro Vera as a you know,
- 9:45Speaker 3: sort of a cocktail. And they they minute so much
- 9:49Speaker 3: they said, we're even stopping this study. But it turns
- 9:52Speaker 3: out there was just a lot of bad reporting about that, right.
- 9:54Speaker 2: Yeah. There's a New York Times magazine article about menopause
- 9:57Speaker 2: by a writer named Susan Dominus, who basically reported that
- 10:04Speaker 2: the media just jumped all over it. There's like, there's
- 10:06Speaker 2: a twenty six percent increased risk in developing breast cancer
- 10:10Speaker 2: if you take Prempro or generally have hormone replacement therapy,
- 10:15Speaker 2: and that's whopping. That's a big, a big number, a
- 10:18Speaker 2: big percentage. But in absolute numbers, it's actually not that big.
- 10:23Speaker 2: So the average woman had a two point three to
- 10:26Speaker 2: three percent chance of developing breast cancer. If you took Prempro,
- 10:30Speaker 2: you had a two point nine to nine percent chance,
- 10:33Speaker 2: So like that was your twenty six percent increase, And
- 10:35Speaker 2: in real terms, it sorted out to, based on the
- 10:38Speaker 2: population at the time, an additional eight women developing breast
- 10:42Speaker 2: cancer out of every ten thousand who were taking replacement hormones.
- 10:46Speaker 2: Nothing to sneeze at those eight women. I'm sure would
- 10:48Speaker 2: much rather prefer not to have breast cancer. But the
- 10:51Speaker 2: point was the risks of it were grossly overstated, and
- 10:55Speaker 2: that it got but it got such a bad rap
- 10:58Speaker 2: because of the reporting that for a couple of decades,
- 11:00Speaker 2: just trust and hormone replacement therapy dropped off and a
- 11:03Speaker 2: lot of women suffered unnecessarily as a result.
- 11:06Speaker 3: Yeah, and I think they didn't even find that the
- 11:10Speaker 3: transdermal variety was in fact much safer than the other
- 11:14Speaker 3: way of taking it.
- 11:15Speaker 2: Yeah, absolutely so, Like if you take it orally, which
- 11:18Speaker 2: is what it was always before, pretty much it has
- 11:21Speaker 2: to go through your liver to be processed, and while
- 11:23Speaker 2: it's there it can do all sorts of nasty stuff
- 11:25Speaker 2: side effects that you don't really want, like causing thrombosis
- 11:29Speaker 2: and blood clots, it can lead to heart disease, whereas
- 11:31Speaker 2: if you do it transdermally, it just enters the bloodstream
- 11:34Speaker 2: and it does its thing with minimal side effects. So
- 11:37Speaker 2: we've reached the point today where your average kind of
- 11:40Speaker 2: coologists is probably going to say the benefits if you're
- 11:44Speaker 2: healthy outweigh the risk of taking it, especially if you
- 11:49Speaker 2: are under age sixty, and especially if you're under age
- 11:53Speaker 2: seventy and you start apparently there's a if you have
- 11:57Speaker 2: a gap between menopause and then start hormone replacement therapy
- 12:01Speaker 2: of a decade or two, then it can become pretty risky.
- 12:05Speaker 2: And by the way, I don't have my lab code
- 12:07Speaker 2: on right now, I would advise you not to take
- 12:09Speaker 2: gecological health advice from me. Instead, ask your doctor. But
- 12:13Speaker 2: this is what I've seen from research.
- 12:15Speaker 3: Yeah, and that, I mean you say that virtually every
- 12:18Speaker 3: time you meet someone in person. I've heard you say
- 12:20Speaker 3: those same words.
- 12:21Speaker 2: I'm big on that for sure.
- 12:23Speaker 3: Say Hi, Josh, nice to meet you. I dude, stuff
- 12:25Speaker 3: you should know. Please don't take onecological advice for me. Yeah,
- 12:28Speaker 3: no matter what comes out of my mouth at this
- 12:30Speaker 3: dinner part.
- 12:31Speaker 2: I mean, it's just a smart thing to say.
- 12:33Speaker 1: It is.
- 12:34Speaker 3: So this is all going on on the ester's in side,
- 12:39Speaker 3: on the testosterone side, and we're gonna, you know, kind
- 12:41Speaker 3: of bop back and forth between.
- 12:43Speaker 1: The two of these.
- 12:45Speaker 3: That was isolated, I believe in nineteen thirty five. In fact,
- 12:50Speaker 3: that's when the name testosterone got its name, which is
- 12:52Speaker 3: sort of the big daddy mail hormone.
- 12:54Speaker 1: And we'll talk about all the versions of these in
- 12:56Speaker 1: a second.
- 12:57Speaker 3: And on its own, testosterone, you know, wasn't doing very much.
- 13:02Speaker 3: But when they added estrone, which is a quote unquote
- 13:05Speaker 3: female hormone, it became very powerful. And in nineteen thirty nine,
- 13:10Speaker 3: there were a couple of guys dude, name I guess
- 13:13Speaker 3: one guy, sorry, Leopold Ruska. Oh no, no, there were
- 13:17Speaker 3: two guys and Adolph Butenant of Germany. They won the
- 13:22Speaker 3: Nobel Prize for chemistry by working on largely testosterone, but
- 13:28Speaker 3: you know sex hormones as a whole. And none other
- 13:31Speaker 3: than mister Adolf Hitler was one of the early adopters
- 13:35Speaker 3: when it came to a testosterone treatment.
- 13:38Speaker 1: Yeah, he had low tit.
- 13:40Speaker 2: I meant to send you this, and I'm sorry I didn't,
- 13:43Speaker 2: but I turned up something that there was in British
- 13:47Speaker 2: World War two military files. There were like a bunch
- 13:51Speaker 2: of ideas of how to like basically take neutralized Hitler,
- 13:55Speaker 2: and one of them was to start slipping estrogen into
- 13:58Speaker 2: his food and that over time it would basically turn
- 14:02Speaker 2: him from a maniac, murderous killer psycho to maybe a
- 14:08Speaker 2: little calmer, maybe a little more feminized. And the whole
- 14:12Speaker 2: idea was that if you put poison in his food,
- 14:15Speaker 2: he had tasters, and the tasters would die from the
- 14:18Speaker 2: poison and he would know that he was being poisoned.
- 14:20Speaker 2: That would not happen with estrogen. It would take place
- 14:22Speaker 2: over such a long time they wouldn't be able to
- 14:24Speaker 2: taste it that that apparently it was never even attempted,
- 14:28Speaker 2: or certainly not carried out, but that was someone's idea
- 14:31Speaker 2: to take care of Hitler. It would have been hilarious, dude,
- 14:35Speaker 2: to see that transition, like had they done that, and
- 14:38Speaker 2: then just to be able to look back all these
- 14:40Speaker 2: years later and watch the progression.
- 14:43Speaker 3: There's a Benny Hill sketch in there somewhere, for sure,
- 14:46Speaker 3: I think so.
- 14:47Speaker 2: So.
- 14:47Speaker 3: Initially, medically speaking, the first use of testosterone was to
- 14:52Speaker 3: try and cure homosexuality in males, which was a needless
- 14:58Speaker 3: to say, it spectacularly back fired because all it did was,
- 15:03Speaker 3: you know, it didn't alter any orientation. It just created
- 15:07Speaker 3: I guess super tops and power bottoms and ramped up
- 15:10Speaker 3: to sex drive. And then of course trans people. This
- 15:14Speaker 3: was you know, very early in the days of hormone
- 15:17Speaker 3: therapy for trans people. It was actually going on, and
- 15:20Speaker 3: in fact, we did a whole episode in April twenty
- 15:24Speaker 3: nineteen called Michael Dillon Trans Pioneer about the Englishman who
- 15:28Speaker 3: was I mean, I think probably the first person at
- 15:33Speaker 3: least from the female to male transition to use that
- 15:36Speaker 3: hormone in nineteen forty.
- 15:37Speaker 2: Yeah, yeah, it definitely was from what we could tell.
- 15:40Speaker 3: And by the way, if you go back and listen
- 15:42Speaker 3: to that episode, if you're like, oh my goodness.
- 15:44Speaker 1: We heard from listeners.
- 15:45Speaker 3: We goofed up the pronouns on that one because we thought,
- 15:49Speaker 3: and this is five years ago, we know better now,
- 15:51Speaker 3: but we thought it would be a good idea to
- 15:53Speaker 3: sort of let the pronouns follow the journey of Michael
- 15:58Speaker 3: Dillon's life. And you know, we know better now, So
- 16:01Speaker 3: just take that with a grain of salt.
- 16:03Speaker 2: Yeah, kid, co. And while we're on that, we should
- 16:05Speaker 2: probably say we're using male and female and man and
- 16:09Speaker 2: woman just generally a shorthand, a biological shorthand. With the
- 16:15Speaker 2: advent of trans people, there there's a much more specific
- 16:18Speaker 2: way of talking about that. Specifically, we would we should
- 16:23Speaker 2: be saying typically developing assigned male at birth or assigned
- 16:27Speaker 2: female at birth, people who haven't altered their hormones. Right,
- 16:32Speaker 2: that's tough to say over and over again, rather than
- 16:34Speaker 2: man or woman. So please forgive us for that. We're
- 16:38Speaker 2: not we're not being disrespectful in that way, and we're
- 16:39Speaker 2: certainly not excluding trans people from this, because this very
- 16:42Speaker 2: much has a lot to do with trans.
- 16:46Speaker 1: Yeah, and well you know that'll come in part too, obviously.
- 16:48Speaker 2: For sure. I say we take a break and come
- 16:50Speaker 2: back and we'll start talking about estrogen.
- 16:53Speaker 1: Let's do it.
- 17:14Speaker 3: All right, So we're back with estrogen. Welcome to the studio, estrogen.
- 17:19Speaker 3: How have you been doing so? That is, usually you
- 17:23Speaker 3: think of estrogen as one of the two female sex
- 17:26Speaker 3: hormones with progesterone, and it is actually a family of
- 17:31Speaker 3: three hormones, the first one being estrone, and that is
- 17:35Speaker 3: the that's not the money estrogen, that's the weakest one menopause.
- 17:41Speaker 3: You know, it keeps getting produced through menopause. It's made
- 17:44Speaker 3: in the adrenal glands, it's made in the ovaries, it's
- 17:47Speaker 3: made in fatty tissue, and it can actually serve as
- 17:50Speaker 3: a sort of a warehouse keeping place for estrogen.
- 17:55Speaker 2: Right, yeah, for sure. So here's where we get to
- 17:58Speaker 2: the idea that it's just misguided. Think estrogen is a
- 18:01Speaker 2: woman's sex hormone and that's it. There's so much more
- 18:04Speaker 2: to it. The whole reason you would continue producing estrogen
- 18:07Speaker 2: as a woman in some form or fashion after menopause.
- 18:11Speaker 2: I mean, if you're not having sex, if you can't
- 18:13Speaker 2: reproduce any longer, why would you produce estrogen? You would
- 18:16Speaker 2: produce a weaker version because it's still doing other things
- 18:19Speaker 2: like it's really important for bone growth and muscle development
- 18:23Speaker 2: and to keep yourself active. There's a lot of stuff
- 18:26Speaker 2: that estrogen does just beyond forming the reproductive system or
- 18:34Speaker 2: for sexing females.
- 18:36Speaker 3: Yeah, and we also did mention and this is probably
- 18:39Speaker 3: if someone wants more quote unquote proof. Estrogen is found
- 18:42Speaker 3: in plants like rice.
- 18:44Speaker 2: Yeah, I mean, we could just end the podcast right here.
- 18:49Speaker 1: Testosterone is not found in plants, only in the animal world.
- 18:51Speaker 3: But we'll get to that, all right. The next one
- 18:53Speaker 3: we come to that was E one. By the way,
- 18:55Speaker 3: E two is estra diol, which is this is the estrogen.
- 19:00Speaker 3: This is the potent one. This is made in the
- 19:03Speaker 3: ovaries of women and made in the testes of men.
- 19:07Speaker 3: Once again, men and women both have each in different levels.
- 19:12Speaker 3: And this is the one that really like kicks in
- 19:14Speaker 3: during puberty and then takes a break during menopause. Not
- 19:19Speaker 3: a break but more like a retirement.
- 19:21Speaker 2: Yeah, it goes to Florida.
- 19:24Speaker 1: Yeah exactly.
- 19:25Speaker 2: Maybe yeah Flora for once. I'm just gonna stick with
- 19:29Speaker 2: my original one. Good Astriol is another one. This one
- 19:34Speaker 2: is mostly produced during pregnancy to help the uterus grow,
- 19:39Speaker 2: and it also helps with breastfeedings. It leads to most
- 19:44Speaker 2: of the body changes during pregnancy. You can thank estriol
- 19:47Speaker 2: for that. And there are other types of estrogen, but
- 19:50Speaker 2: typically it's those three. Those are the big ones. And
- 19:53Speaker 2: it's obviously everyone knows estrogen is the reason that you
- 19:57Speaker 2: have breasts and that your hips fill out, and that
- 20:00Speaker 2: it has a lot to do with a woman's monthly cycle, right,
- 20:04Speaker 2: And that's absolutely true. That has a lot to do
- 20:06Speaker 2: with everything, like that's what estrogen does. But it is
- 20:09Speaker 2: again it's important for metabolizing muscles, for preventing your muscles
- 20:15Speaker 2: from injury. It also contributes to endurance, which if you
- 20:20Speaker 2: read about ultra marathons, women tend to dominate those I
- 20:24Speaker 2: was reading about, Like short runs, men can outrun women
- 20:28Speaker 2: very easily. Marathons typically men win. But then as you
- 20:32Speaker 2: get further and further and further, and actually there's a
- 20:35Speaker 2: moment I think it's like like one hundred and fifty
- 20:39Speaker 2: miles or some mind boggling amount of distance, women start
- 20:43Speaker 2: to slowly overtake men. And then the longer you go,
- 20:46Speaker 2: the further ahead, women finish before men in tests of
- 20:52Speaker 2: endurance like that, and they think it's because they have
- 20:54Speaker 2: higher stores of estrogen, which is helping their muscles work better.
- 20:59Speaker 3: So you talked about good for like you know, muscle
- 21:02Speaker 3: growth and muscle formation. Sure, Also estrogen can help facilitate
- 21:07Speaker 3: brain activity, skin elasticity, which you know, is that why
- 21:14Speaker 3: like wrinkles happen as you age? Is that because of
- 21:17Speaker 3: drop and among other things in estrogen?
- 21:20Speaker 2: I would think so. I think it's also just they've
- 21:22Speaker 2: been around the block so many times, like skin, I mean.
- 21:27Speaker 1: Yeah, yeah, So if you're a doctor, doctor Clark.
- 21:31Speaker 2: Well, no, okay, why am I?
- 21:34Speaker 3: Why am I going wrinkley around the eyes here? What's
- 21:37Speaker 3: going on with physiologically with my body? You know, it's
- 21:39Speaker 3: been around the block?
- 21:41Speaker 1: What more? What more can I say? And also, don't
- 21:43Speaker 1: take any gynecological advice from me.
- 21:46Speaker 2: Right, I'd be like, I thought you're a dermantologist. Oh
- 21:48Speaker 2: I'm neither.
- 21:49Speaker 1: Oh boy.
- 21:50Speaker 3: So estrogen is something that can affect mood, but you
- 21:54Speaker 3: know it's it fluctuates. I think pre menopausal women have
- 22:00Speaker 3: a range of about thirty to forty pikeograms per mili liter,
- 22:05Speaker 3: But it varies from person to person. And then like
- 22:08Speaker 3: we said, it rises and falls during the menstrual cycle.
- 22:11Speaker 3: It's not like a set number. I think Postman Apostle
- 22:15Speaker 3: that drops all the way down from literally zero to thirty.
- 22:20Speaker 1: And then for.
- 22:21Speaker 3: Men, for guys like you and me, yeah, we have
- 22:23Speaker 3: a range of about ten to fifty. I'm probably more
- 22:26Speaker 3: like fifty five or sixty would be my guess.
- 22:30Speaker 2: So I'm right there with you, buddy. So again, the
- 22:33Speaker 2: reason why men would have it at all is because
- 22:35Speaker 2: it's not just the woman's sex a female sex hormone.
- 22:39Speaker 2: It does other stuff. Just I can't say this enough
- 22:42Speaker 2: because it was such a sure you can like it,
- 22:45Speaker 2: It was such an epiphany for me. I'm just like, Oh,
- 22:49Speaker 2: I had no idea that it was this, that things
- 22:52Speaker 2: overlap this much. Yeah, I mean I didn't think it
- 22:55Speaker 2: was just like cut and dry, but I knew there
- 22:57Speaker 2: was some crossover, but I didn't realize just how much
- 23:00Speaker 2: Steinbach screwed us up with that whole binary thing.
- 23:05Speaker 1: Yeah.
- 23:05Speaker 3: I was trying to make a joke about a pop
- 23:07Speaker 3: act that crossed over, but I couldn't come up with it.
- 23:11Speaker 1: Just, uh, someone send in a good joke there.
- 23:13Speaker 2: How about Bay Bay Beyonce in the country.
- 23:17Speaker 1: I heard about that, did you hear it? Is it good? Yeah?
- 23:20Speaker 2: It's fine. I'm not huge in the country.
- 23:23Speaker 1: So it's real country then, huh.
- 23:25Speaker 2: No, it's like dance floor line dancing hunt. Yeah, sure
- 23:30Speaker 2: it is real country. Yes, but it's not like it's
- 23:33Speaker 2: not like Hank or anything like that. But it's like
- 23:35Speaker 2: a it's more like Garth. It's like a Garth Brooks song.
- 23:38Speaker 1: Oh geez, I need to hear it.
- 23:39Speaker 3: I thought it was more just like Hi and Beyonce
- 23:42Speaker 3: and I put on a cowboy hat.
- 23:43Speaker 2: So now, no, she's from Texas. You know she knows
- 23:45Speaker 2: what she's talking about.
- 23:46Speaker 1: Yeah, that's true. Can we talk about the Big.
- 23:49Speaker 2: Don't please don't quote me on that. I'm not in
- 23:51Speaker 2: the bay Hive.
- 23:53Speaker 1: Okay, I went to that concert. Was great.
- 23:56Speaker 2: Yeah, I'll bet. Can we talk about the Big t
- 24:00Speaker 2: Oh we're here? Huh yeah.
- 24:02Speaker 3: I mean we're going to go back and forth. But
- 24:04Speaker 3: T needs to he needs this tea is ready to speak.
- 24:06Speaker 2: I think before we do, I want to say one
- 24:08Speaker 2: other thing about estrogen. It apparently encourages physical movement, and
- 24:12Speaker 2: you're like, so like with low estrogen, your will to
- 24:17Speaker 2: get up and move or walk across the room or
- 24:20Speaker 2: go take a walk is depleted because your estrogen is lower.
- 24:25Speaker 2: It's as simple as that Isn't that nuts? Yeah, that's cool.
- 24:29Speaker 2: So yes, now we're on to tea.
- 24:31Speaker 1: That's right, the male hormone in.
- 24:35Speaker 2: Part, Yes, and that's no joke. Like, for sure, estrogen
- 24:39Speaker 2: helps form females, Testosterone helps form males, and apparently in
- 24:47Speaker 2: the uterus they're both exposed to copious amounts of testosterone.
- 24:52Speaker 2: It's just what differentiates females from males or keeps females
- 24:56Speaker 2: from developing into males. Because I didn't know this either, Chuck.
- 25:00Speaker 2: We all start out as females. Did you know that.
- 25:04Speaker 1: I think we talked about that in our puberty episode.
- 25:06Speaker 2: Okay, so just bear with me for a second. We
- 25:08Speaker 2: all start out as females, and then we're all we're
- 25:12Speaker 2: all kind of inundated with testosterone. But females typically have
- 25:17Speaker 2: something called aromatase, which is an enzyme that converts testosterone
- 25:21Speaker 2: into estrogen much more prevalent in the feed in the
- 25:26Speaker 2: placenta with the fetus, and so it's basically like batting
- 25:29Speaker 2: away all the testosterone. So the baby comes out assigned
- 25:33Speaker 2: female at birth. Pretty interesting, huh. Like without the injection
- 25:37Speaker 2: of testosterone, we would all be females or without the
- 25:40Speaker 2: presence of aromatase, we would all be males.
- 25:44Speaker 1: That's right.
- 25:45Speaker 3: And then once things are you know, I guess what
- 25:47Speaker 3: that's around the seventh week or.
- 25:49Speaker 2: So, yeah, something like that.
- 25:51Speaker 1: That's when the testicles start to produce testosterone. That's when the.
- 25:54Speaker 3: Factory opens up. And I don't think we mentioned, but
- 25:58Speaker 3: testosterone is a member of a family of androgen hormones. Uh,
- 26:04Speaker 3: boy to should we even try and say these or
- 26:06Speaker 3: just say the shorthand? I want to say them, knock
- 26:09Speaker 3: yourself out?
- 26:10Speaker 2: Uh andros stenny dione then I practiced and st andres
- 26:17Speaker 2: steno dione.
- 26:18Speaker 1: Yeah, I think that's right.
- 26:19Speaker 2: D hydro epi andros sterone also known as dh A sure,
- 26:24Speaker 2: d hydro epi androsterone sulfate d h A, yes, and
- 26:29Speaker 2: then dihydro testosterone d h T.
- 26:31Speaker 1: Yeah. Nice work.
- 26:33Speaker 3: Thanks, you get to move on in our medical competition.
- 26:37Speaker 2: You could be a doctor, but but I'm not. So
- 26:40Speaker 2: don't that's forgotten logical.
- 26:42Speaker 1: Advice, never never or any medical advice.
- 26:45Speaker 3: Uh So, Like I said, the test testosterone factory is
- 26:49Speaker 3: open at about seven weeks. And the reason we went
- 26:52Speaker 3: back and kind of named the others is because some
- 26:54Speaker 3: of that testosterone at that age is converted into the dhea. Right, yeah,
- 27:03Speaker 3: I'm not gonna say it. And that is the sort
- 27:07Speaker 3: of the money hormone for making the penis form and
- 27:11Speaker 3: grow in the prostate. And about seven months in is
- 27:15Speaker 3: when the trigger is kicked off by testosterone for testicular descent.
- 27:21Speaker 3: Even though that can happen after you're born.
- 27:23Speaker 2: It makes it hilarious. Beew sound.
- 27:26Speaker 1: Oh man, where's your slide whistle?
- 27:28Speaker 2: I don't have it on me. Maybe gerial'll work it in.
- 27:32Speaker 3: Yeah, I think you actually isolated some slide whistle cuts,
- 27:35Speaker 3: so don't.
- 27:36Speaker 2: Tell everybody I know. Here's one of the facts of
- 27:40Speaker 2: the podcast. To me. I had no idea about this.
- 27:43Speaker 2: But so male babies are flooded with testosterone. They don't
- 27:48Speaker 2: have a bunch of aromatase to convert all of it
- 27:51Speaker 2: into estrogen, so they become male and all the stuff
- 27:55Speaker 2: that you just mentioned happens. But they do have some aromatase,
- 28:00Speaker 2: and some of that testosterone is converted into estra diol,
- 28:03Speaker 2: and that estra dial actually is what forms the male brain.
- 28:09Speaker 2: So estrogen forms the male brain starts out as testosterone
- 28:13Speaker 2: converted into estratiol. It causes the changes in the brain
- 28:17Speaker 2: that create.
- 28:18Speaker 1: The male brain whatever, snowflake.
- 28:21Speaker 2: I just think that's awesome. Like it also just goes
- 28:25Speaker 2: to show you, like just how so, I mean, just
- 28:28Speaker 2: imagine what an intricate chemical dance this is and how Yeah,
- 28:33Speaker 2: you just adjust this a little bit and adjust that
- 28:35Speaker 2: a little bit and all sorts of different outcomes can happen.
- 28:37Speaker 2: It's just fascinating, Oh for sure.
- 28:40Speaker 3: I mean, when you're a little kid, there's not a
- 28:43Speaker 3: lot of difference between your testosterone levels. If you're a
- 28:47Speaker 3: little girl a little boy, I think usually under ten
- 28:50Speaker 3: nanograms per desolators at puberty where things just go hog wild, right,
- 28:56Speaker 3: and little boy's testosterone just shoots through the roof. It
- 29:00Speaker 3: rises in girls as well, but nothing like it does
- 29:03Speaker 3: in boys. Once you become a big man, a full
- 29:07Speaker 3: grown man like us, you're gonna have tea levels between
- 29:11Speaker 3: three hundred and a thousand, if you know, if you
- 29:14Speaker 3: have normal quote unquote normal tea. Women have much lower
- 29:17Speaker 3: levels between fifteen and seventy. And this is you know,
- 29:21Speaker 3: in little boys, what's gonna trigger your voice to change,
- 29:25Speaker 3: your bone and muscle mass to grow. You're you know,
- 29:29Speaker 3: all of a sudden, you're gonna have body hair and
- 29:31Speaker 3: facial hair and stuff like that. And also, and I
- 29:34Speaker 3: think we've talked about this at some point, but it
- 29:37Speaker 3: is related to male pattern baldness. But I don't think
- 29:40Speaker 3: they're still at the level where they can say like, hey,
- 29:43Speaker 3: if you have high tee, then you're more likely to
- 29:46Speaker 3: be bald.
- 29:47Speaker 2: Yes. And that's really really important to point out, dude,
- 29:51Speaker 2: is that we are not at a place in microbiology
- 29:56Speaker 2: or human chemistry or we're like, this is what this
- 29:58Speaker 2: hormone does, and this is what that hormone and dones.
- 30:00Speaker 2: And one of the reasons why is because the same
- 30:02Speaker 2: hormone can have wildly different effects depending on at what
- 30:07Speaker 2: stage in a reaction it comes in, or in what
- 30:10Speaker 2: tissues or what regions of the brain or the body
- 30:13Speaker 2: it's interacting with other things. So when you add all
- 30:16Speaker 2: these different not just other kinds of hormones, but also
- 30:19Speaker 2: like neurotransmitters or neuromodulators and all this stuff, it just
- 30:22Speaker 2: becomes exponentially more complicated and complex. So we're still kind
- 30:27Speaker 2: of at the place where it's like, yeah, testosterones for
- 30:30Speaker 2: boys and estrogens for girls, and we're making tons of headway,
- 30:35Speaker 2: but generally speaking, we're still at a very basic level
- 30:38Speaker 2: and understanding what hormones are capable of. And then also
- 30:43Speaker 2: on the flip side, looking at behavior and saying like, oh, well,
- 30:46Speaker 2: clearly aggression is related to high levels of testosterone.
- 30:51Speaker 3: Yeah, and we'll get to that coming up in a
- 30:53Speaker 3: sect for short with there been lots of studies, Well,
- 30:56Speaker 3: we need to talk about testosterone dropping over the years,
- 30:59Speaker 3: because men don't experience like a drop off in testosterone
- 31:04Speaker 3: like women do with menopause and estrogen. But it does
- 31:09Speaker 3: decline in both men and women testosterone by about a
- 31:11Speaker 3: percentage a year starting in your thirties, sort of early
- 31:16Speaker 3: to mid thirties generally, although that can vary as well,
- 31:19Speaker 3: and it can vary just from time to time too.
- 31:22Speaker 3: A man's level of testosterone can go up or down
- 31:26Speaker 3: fairly dramatically for different reasons over short periods of time.
- 31:30Speaker 2: Yeah, And just like with estrogen, testosterone is also responsible
- 31:34Speaker 2: for bone growth and development in remodeling, apparently, the testosterone
- 31:38Speaker 2: is useful for the hard outer layers of the bone
- 31:42Speaker 2: and estrogen is for the spongy interior layers. It's cool
- 31:47Speaker 2: and also something else that stood out to me is
- 31:49Speaker 2: men's estrogen levels are roughly similar to women's testosterone levels
- 31:55Speaker 2: under normal circumstances. Yeah, I guess so, right, Yeah, I
- 31:59Speaker 2: think it's pretty interest.
- 32:00Speaker 1: I think I'm looking at the numbers.
- 32:01Speaker 2: Did they add up?
- 32:03Speaker 3: Well, you were talking about aggression. I mean, should we
- 32:07Speaker 3: take a break and talk about that or should we wait?
- 32:09Speaker 2: I say we take a break. Now, we've already the
- 32:11Speaker 2: monkey's already flown the.
- 32:13Speaker 3: Coup, right, all right, the monkey's out of the bag,
- 32:16Speaker 3: the cat is out of the cage.
- 32:18Speaker 1: We'll be right back.
- 32:40Speaker 2: Okay, Chuck, So we're back. We found the cat, put
- 32:42Speaker 2: them in the cradle with the silver spoon, so everything's
- 32:45Speaker 2: back to normal.
- 32:46Speaker 1: Sad a song?
- 32:48Speaker 2: Oh it is? It is pretty said, especially if you
- 32:49Speaker 2: like your dad.
- 32:52Speaker 1: Especially if you had problems with your dad.
- 32:54Speaker 2: Oh yeah, I guess so, I guess so.
- 32:56Speaker 1: Yeah.
- 32:57Speaker 2: Yeah. Is there any circumstance where that wouldn't be a sad?
- 33:00Speaker 1: I don't know.
- 33:01Speaker 3: Maybe the perfect amount of care and love from your
- 33:05Speaker 3: father and with no accompanying.
- 33:09Speaker 2: Abuse, gotcha, perfect?
- 33:11Speaker 1: I don't know.
- 33:12Speaker 2: I'm sure that's very prevalent. Yeah. So, yeah, we're talking
- 33:15Speaker 2: about testosterone, we're talking about sex, we're talking about aggression.
- 33:20Speaker 2: All of those things seem to be very much intertwined
- 33:23Speaker 2: in the public consciousness about testosterone. Right, the more testosterone
- 33:27Speaker 2: you have, the more stillone esque you are, the more
- 33:31Speaker 2: likely you are to wear like a floor length mink
- 33:34Speaker 2: coat with no shirt underneath, which I have to say,
- 33:37Speaker 2: if I could wear that, I definitely would, if I
- 33:39Speaker 2: could rock that look. It's a good look.
- 33:41Speaker 3: And Josh, I think if you remember, I wore that
- 33:43Speaker 3: exact coat in the movie, in my film Nighthawks, is
- 33:46Speaker 3: that what happens from I think you are mink coat
- 33:49Speaker 3: in Nighthawks?
- 33:50Speaker 1: Okay, although he was a cop in Nighthawks. You can
- 33:52Speaker 1: afford a mink coat.
- 33:53Speaker 2: No way, not on a cop salary, not an honest cop,
- 33:57Speaker 2: an underrated movie. So is it?
- 34:00Speaker 3: Yeah, I don't know if it holds up great, but
- 34:02Speaker 3: I thought it had a pretty good ending. We won't spoil.
- 34:05Speaker 2: No, no, it's and it's definitely spoilable for sure.
- 34:08Speaker 3: But and that was my st alone. By the way,
- 34:10Speaker 3: people are just like, what are you even talking about?
- 34:12Speaker 3: Why did Chuck slur there?
- 34:14Speaker 2: For a little while, I thought it came through loud
- 34:15Speaker 2: and clear. Okay, But the idea is that, like the
- 34:18Speaker 2: whole reason the Rambo films were made, particularly two and three,
- 34:22Speaker 2: is because Sylvester still own experienced a massive spike in testosterone.
- 34:26Speaker 2: It had to get it out in some productive way, right.
- 34:29Speaker 1: Oh, I thought it was because Rambo was no expendable.
- 34:33Speaker 2: I haven't seen those movies.
- 34:35Speaker 1: Huh No, no, no, it was a joke from Rainbow two.
- 34:38Speaker 2: Oh well, he was also in the Expendables.
- 34:40Speaker 1: Yeah, I know. I wonder if that had anything to
- 34:42Speaker 1: do with that line.
- 34:43Speaker 2: Probably not, It could be at I'm sure there's some
- 34:47Speaker 2: people who are like, shut up and talk about aggression
- 34:51Speaker 2: in testosterone, you're making me aggressive.
- 34:54Speaker 1: Well, what if you knew to a male dog. That's
- 34:56Speaker 1: a good sort of first example.
- 34:57Speaker 2: That's a great entree, Chuck. Most people would say that
- 35:02Speaker 2: if you neuter, if you remove the testicles of a
- 35:05Speaker 2: male dog, it's going to become much more submissive, much chiller,
- 35:09Speaker 2: probably a lot more fun at parties, will come pick
- 35:13Speaker 2: you up if your car breaks down, that kind of thing.
- 35:16Speaker 2: And there is some data that shows that that's the case,
- 35:19Speaker 2: that some dogs are calmer once they're neutered, But the
- 35:24Speaker 2: other studies have shown like the exact opposite is true,
- 35:28Speaker 2: that dogs can become actually more aggressive when they're neutered,
- 35:31Speaker 2: which is a head scratcher of a puzzler if you
- 35:34Speaker 2: ask me.
- 35:34Speaker 3: Yeah, I mean I just went through this with Gibson,
- 35:37Speaker 3: and he's not more aggressive because that's an aggressive is
- 35:43Speaker 3: a weird word, because aggressive isn't the same thing as like,
- 35:46Speaker 3: you know, heaper now just like an excitable puppy, Like
- 35:51Speaker 3: that's not aggression necessarily. Yeah, but it definitely did not
- 35:55Speaker 3: chill him out at all.
- 35:57Speaker 2: Yeah. Yeah, I don't know that it's supposed to, but yeah,
- 36:00Speaker 2: I think some people think it does. But the idea
- 36:03Speaker 2: that it would make a dog more aggressive, so it
- 36:06Speaker 2: had like no impact on him as far as like
- 36:08Speaker 2: his energy level is what you're saying. Yeah, so imagine
- 36:13Speaker 2: if he was generally like that before and then you
- 36:16Speaker 2: neuted him and then he started like biting people. Yeah,
- 36:18Speaker 2: that's that's what happens with some dogs. And they're like, well,
- 36:21Speaker 2: that doesn't make any sense whatsoever. One of the explanations
- 36:24Speaker 2: is is that we think testosterone is tied up with
- 36:28Speaker 2: confidence more than aggression, and that a dog that has
- 36:32Speaker 2: this chemical confidence removed through neutering can actually become more
- 36:38Speaker 2: more nervous, and nervous dogs frequently will bite or bark
- 36:41Speaker 2: more than they did when they had confidence via testosterone.
- 36:46Speaker 3: Yeah, and that ties in perfectly to the fact that
- 36:49Speaker 3: and this to me is one of the facts of
- 36:51Speaker 3: the show. But they have done studies and male athletes,
- 36:55Speaker 3: like you know, superior male athletes, actors, it or not,
- 37:00Speaker 3: blue collar workers and confidence artists, con men, they all
- 37:05Speaker 3: have above average levels of testosterone.
- 37:08Speaker 2: Yeah, so there you have it, so too, all right,
- 37:11Speaker 2: case closed, So too though, And this is the state
- 37:14Speaker 2: of study right now with studying the stuff where we're
- 37:19Speaker 2: relating human behavior to hormones like testosterone or estrogen, Like,
- 37:24Speaker 2: there's results like that out there, but that we arrive
- 37:28Speaker 2: at the question, well, wait a minute, do people who
- 37:31Speaker 2: have higher levels of testosterone naturally gravitate to those professions
- 37:36Speaker 2: or does being in a profession like acting or being
- 37:39Speaker 2: a con man raise your testosterone life? Right, They're like, well,
- 37:42Speaker 2: hold on, okay, I got this. We're going to go
- 37:44Speaker 2: study prisoners, specifically violent criminal offenders and see what their
- 37:49Speaker 2: testosterone levels are.
- 37:51Speaker 1: Like.
- 37:51Speaker 2: Sure enough, they found that their testosterone levels were above average,
- 37:56Speaker 2: But that still raises the question do higher levels of
- 38:01Speaker 2: testosterone make you more prone to any social violent behavior?
- 38:05Speaker 2: Or does being in prison raise your levels of testosterone.
- 38:08Speaker 2: We still don't know at this point.
- 38:10Speaker 1: Yeah.
- 38:11Speaker 3: Yeah, it's pretty interesting because I think a lot of people,
- 38:13Speaker 3: like the generals, just the old way of thinking was like,
- 38:16Speaker 3: of course.
- 38:16Speaker 2: It does, right, And you know what they're finding, they
- 38:20Speaker 2: think is that it's more that testosterone is released when
- 38:26Speaker 2: you need it.
- 38:27Speaker 1: Yeah, it meets the occasion.
- 38:29Speaker 2: Right, It's not the thing that's driving the behavior. It's like, oh,
- 38:32Speaker 2: this guy says it's go time, we better release some
- 38:34Speaker 2: testosterone to keep it going.
- 38:36Speaker 3: Yeah, this next thing is super interesting to me. You know,
- 38:42Speaker 3: moment to moment throughout your day, you're gonna your testosterone
- 38:44Speaker 3: is going to rise and fall some. And they have
- 38:48Speaker 3: found that if you lose, like a running race or
- 38:53Speaker 3: a one on or a basketball game, or an arm
- 38:56Speaker 3: wrestling match, or even a chess match, you will lose testosterone.
- 39:03Speaker 3: So it's not even necessarily it can be something as
- 39:05Speaker 3: cerebral as a chess match, but losing reduces your testosterone.
- 39:10Speaker 3: Winning increases and boosts your testosterone. And they even found
- 39:15Speaker 3: this is crazy to me, that they sampled male voters
- 39:20Speaker 3: for like an election and just your candidate losing causes
- 39:25Speaker 3: a drop in testosterone.
- 39:28Speaker 2: Yeah, isn't that nuts? That was among McCain voters because
- 39:32Speaker 2: it was the two thousand and eight election. Yeah, it's crazy.
- 39:36Speaker 3: Yeah, it's like it's unbelievable, like winning and losing even
- 39:39Speaker 3: if you're not participating other than voting yes.
- 39:43Speaker 2: So they also found that they think that social expectations
- 39:50Speaker 2: can kind of modulate behavior, right, and this kind of
- 39:54Speaker 2: ties into that idea that testosterone kind of helps foster
- 39:59Speaker 2: a response rather than triggering a response, right. So essentially
- 40:04Speaker 2: what they found is that with testosterone levels, we can
- 40:08Speaker 2: correlate it as far as if you are having if
- 40:11Speaker 2: you're faced with a fight or flight situation and you
- 40:14Speaker 2: choose to fight, you probably are experiencing an up tick
- 40:18Speaker 2: in testosterone levels. Again that you didn't have testosterone and
- 40:22Speaker 2: now you're choosing to fight. They think the exact opposite
- 40:25Speaker 2: is true, that you've chosen to fight and your testosterone
- 40:28Speaker 2: levels go up. On the other hand, they found that
- 40:31Speaker 2: if you choose to flee or say not be aggressive,
- 40:34Speaker 2: your cortisol levels, your stress hormone levels increase. So our
- 40:39Speaker 2: response seems to be based on what we think society
- 40:42Speaker 2: will either reward or punish, and then based on our
- 40:46Speaker 2: decision from that our hormones kick in to help kind
- 40:49Speaker 2: of carry out whichever response we decide to go with.
- 40:52Speaker 2: So one other thing that I found was that that
- 40:55Speaker 2: surprised me is that testosterone isn't just made in like
- 40:59Speaker 2: the t testies or the ovaries depending on your sex
- 41:02Speaker 2: assigned a birth, but that it's actually made locally in
- 41:06Speaker 2: the brain, and that testosterone can also be transformed into
- 41:10Speaker 2: different types of estrogen in the brain too, And they
- 41:13Speaker 2: think that locally produced is what it's called testosterone in
- 41:17Speaker 2: like our neural pathways, has much more of an effect
- 41:21Speaker 2: on behavior, mood, that kind of stuff than the stuff
- 41:24Speaker 2: that's made in the testes or the ovaries, and that
- 41:27Speaker 2: actually accounts for some of the baffling results we've gotten
- 41:30Speaker 2: where you know, if you take a blood sample of
- 41:33Speaker 2: somebody and find that they were just being aggressive, but
- 41:37Speaker 2: their blood doesn't show any kind of spike and testosterone, well,
- 41:40Speaker 2: that would account for that because it's not the stuff
- 41:42Speaker 2: that's floating around in their blood that's making them do that.
- 41:45Speaker 2: It's the locally produced testosterone in their brain that's you know,
- 41:49Speaker 2: connecting with their amygdala or something like that it's making
- 41:52Speaker 2: that's helping them their aggressiveness, I guess alone.
- 41:56Speaker 3: And now I know everyone wants to get to the
- 41:59Speaker 3: part about sex and what testosterone does there. And testosterone does,
- 42:05Speaker 3: you know, sort of directly ramp up the sex drive
- 42:07Speaker 3: in men and women. And they have done trials where
- 42:11Speaker 3: they have shown that it increases the libido. But just
- 42:16Speaker 3: because your tea falls doesn't necessarily mean it's going to
- 42:20Speaker 3: decrease your libido. It can, but it doesn't mean it
- 42:24Speaker 3: has to.
- 42:25Speaker 2: Right. Yeah, Again, that's just there's baffling results we get
- 42:30Speaker 2: sometimes from just studies of what we presume has to
- 42:35Speaker 2: do with testosterone or estrogen, and it just doesn't quite job.
- 42:40Speaker 3: All right, So I guess now we can sort of
- 42:41Speaker 3: finish up with some talk of intersex people and where
- 42:46Speaker 3: we stand now with hormone therapy, right.
- 42:48Speaker 2: Yeah, because one group there's a lot of different people
- 42:51Speaker 2: besides postmenopausal or perimenopausal women who take hormone replacement therapy,
- 42:58Speaker 2: intersex people, people who are born with ambiguous genditalia. Because
- 43:02Speaker 2: like we'd mentioned that whole amazingly intricate dance of chemicals
- 43:06Speaker 2: and hormones during development. Fetal development can just take one
- 43:11Speaker 2: step to the left or one step to the right,
- 43:13Speaker 2: and all of a sudden, there's just a different outcome
- 43:15Speaker 2: that happens to some people. And some people take hormone
- 43:18Speaker 2: replacement therapy to either become more like the gender they
- 43:24Speaker 2: presume that they would have been assigned at birth, or
- 43:26Speaker 2: the gender that they feel like they were assigned at
- 43:28Speaker 2: birth but their genitalia doesn't quite match. There's a lot
- 43:31Speaker 2: of different outcomes that are basically considered conditions that you
- 43:35Speaker 2: can kind of help alleviate with hormone replacement.
- 43:37Speaker 1: Yeah, for sure. Another one.
- 43:39Speaker 3: And I'm pretty sure we talked about this in our
- 43:42Speaker 3: female puberty episode. Was starting the nineteen forties, and maybe
- 43:46Speaker 3: even before that, estrogen therapy and hormone treatment could help.
- 43:52Speaker 3: Basically what they would say, like, you know, you don't
- 43:55Speaker 3: want your daughter to grow too tall, so they would
- 43:58Speaker 3: use a hormone block. You don't see that as much today.
- 44:02Speaker 3: It was called precocious puberty, which is still.
- 44:04Speaker 1: A thing that can happen.
- 44:05Speaker 3: I think if you enter puberty, I think it's like
- 44:07Speaker 3: a year or two two or what's considered too early,
- 44:10Speaker 3: or you know, just with outside of the normal range.
- 44:14Speaker 3: You can also use these hormone blocking drugs. I mean
- 44:19Speaker 3: they still use in today, but that it's not like
- 44:21Speaker 3: say you don't grow too tall. It's basically just to
- 44:23Speaker 3: save off puberty and to halt precocious puberty in its tracks. Also,
- 44:28Speaker 3: if you are a trans kid, you can use a
- 44:31Speaker 3: hormone blocker to just sort of hit the pause button
- 44:34Speaker 3: to give you a little time to decide what kind
- 44:36Speaker 3: of puberty to go through.
- 44:38Speaker 2: Yeah, because once you go through puberty, particularly if you
- 44:42Speaker 2: think it was the wrong puberty for the gender you
- 44:45Speaker 2: identify with, there are going to be changes that are
- 44:49Speaker 2: essentially irreversible aside from surgery. Like if you go through
- 44:53Speaker 2: female puberty but you're a trans male, you're still going
- 44:58Speaker 2: to have breasts that half to be removed. Or if
- 45:01Speaker 2: you're a trans woman and you went through male puberty,
- 45:03Speaker 2: your vocal cords are gonna think you're gonna have a
- 45:05Speaker 2: deeper voice, and maybe an atom's apple surgery will have
- 45:07Speaker 2: to remove that. That's how powerful the hormones that get
- 45:11Speaker 2: released and the amounts that they get released in during puberty.
- 45:15Speaker 2: So if you're not quite sure which gender you belong
- 45:18Speaker 2: to yet, using hormone blockers can actually help kind of,
- 45:22Speaker 2: like you said, buy you some time until you figure
- 45:24Speaker 2: out which way you want to go.
- 45:26Speaker 3: Yeah, and as far as testosterone therapy goes, if you
- 45:30Speaker 3: have a deficiency and testosterone because of hypogonatism or maybe
- 45:35Speaker 3: from HIV or something like that, it's obviously gonna help
- 45:39Speaker 3: with that. Also problems like and here's where it gets
- 45:42Speaker 3: a little tricky, depression, low muscle mass, low energy. There's
- 45:48Speaker 3: some evidence that can prove sexual function, but not as
- 45:50Speaker 3: much that it can increase your low energy if you're
- 45:53Speaker 3: just sort of losing testosterone at that normal rate of
- 45:57Speaker 3: like one what was it, I can't remember.
- 46:00Speaker 2: The one percent a year? I think is it?
- 46:03Speaker 3: Yeah, one percent a year. But if you have an
- 46:06Speaker 3: actual deficiency, they've shown that it can improve sexual function
- 46:10Speaker 3: and just don't have as much proof with energy level.
- 46:14Speaker 2: So does that mean that the ad that has Frank
- 46:16Speaker 2: Thomas and Doug Flutie in it talking about how they're
- 46:19Speaker 2: like crushing their workouts that actually doesn't work. Well.
- 46:22Speaker 3: I don't know if they're just saying if they're claiming
- 46:25Speaker 3: they're just having natural decline in age, or if they
- 46:27Speaker 3: had a deficiency to begin with, because that's that seems
- 46:30Speaker 3: to be the differentiating factor.
- 46:32Speaker 2: Yeah, for sure, Yeah, who knows.
- 46:34Speaker 1: I mean, let's call up Doug Flutie in.
- 46:36Speaker 2: Let's get him on the horn exactly. Uh, you got
- 46:39Speaker 2: anything else?
- 46:41Speaker 1: Uh no, I got nothing else.
- 46:43Speaker 2: I got nothing else either. This is a very enlightening
- 46:45Speaker 2: podcast episode. I should say a lot of stuff I
- 46:49Speaker 2: didn't know about, and now I know more, and you
- 46:51Speaker 2: still shouldn't take my advice medically speaking. Never since Chuck
- 46:56Speaker 2: said never after a nice hearty chuckle, it means it's
- 46:59Speaker 2: time for listener may.
- 47:03Speaker 3: Hey, guys, I was turned on your show about six
- 47:05Speaker 3: months ago and have been rapidly consuming multiple episodes each
- 47:08Speaker 3: day going back and forth to work. I heard the
- 47:12Speaker 3: school bus yellow episode this morning and thought you might
- 47:15Speaker 3: not have found this little nugget you pointed out mister
- 47:18Speaker 3: Sear Sire was credited with the standardization. I believe you
- 47:23Speaker 3: also noted some other districts had already turned to bright
- 47:25Speaker 3: paint jobs on school buses. But on March twenty third,
- 47:28Speaker 3: nineteen thirty one, the Pleasant Hill tragedy near town Or,
- 47:30Speaker 3: Colorado was because I had a blizzard that came in
- 47:34Speaker 3: that morning. School shut down sent the kids home, and
- 47:36Speaker 3: one of the school buses ran off the road, stuck
- 47:39Speaker 3: in the snow for thirty plus hours. Resulting in the
- 47:42Speaker 3: death of five of the twenty students and the bus driver.
- 47:44Speaker 2: Oh my god.
- 47:45Speaker 3: The aftermath theorized that a brightly painted school bus would
- 47:48Speaker 3: have been much easier to spot in the white out
- 47:50Speaker 3: and might not have sat waiting so long to be found.
- 47:53Speaker 3: So buses in Colorado adopted the yellow standard by nineteen
- 47:56Speaker 3: thirty nine, and the proposal for Mister Sire became a
- 48:01Speaker 3: national standard. Unfortunately, it was a reactive, not proactive solution,
- 48:06Speaker 3: brought on by a spring blizzard on the plains of
- 48:09Speaker 3: eastern Colorado. That is from John Colts, and I was
- 48:13Speaker 3: just curious John didn't say I guess that.
- 48:15Speaker 1: School bus might have been white.
- 48:17Speaker 2: I would think so.
- 48:19Speaker 1: Yeah, not a great color.
- 48:20Speaker 2: No, No, for sure. Thanks a lot, John, That was
- 48:23Speaker 2: a really amazing email. I never heard of that one.
- 48:25Speaker 2: That's terrible. If you want to bring us down terribly
- 48:28Speaker 2: like John did, you can send us an email, wrap
- 48:31Speaker 2: it up, spank it on the bottom, and send it
